For bike rental we refer to our collegeas at 5 min. walk from Ambrosia:
– Chez marie, on the main square, just in front of the tourist office.
– Bikingbox (also electric bicycles), between the main square and the Menin Gate.
The landscape is rather flat with some hills as well. The entire area offers a decent cycle route network. Bike rental in Ypres is definetely one of the things to consider! There are some proposed cycling routes like the peaceroute and the Ypressalientroute. Most used are the junctions.
